Ever since I got the firmware update to version 4.1.2 my device started acting a little strange. I noticed that when I reach out to the phone, the screen no longer lights up to display information (like it normally would show a 'quick glance' of number of emails, calls, etc..), but instead a blue led start blinking. When I turn the screen back on it stops blinking and there are no notifications, no messages, nothing. I rather not turn off LED notifications since I do want to receive real notifications. This is not a notification since I am not notified of anything other than a blue flashing LED that disappears when the screen is back on, whatever that means.
